You can try PRO features within the free Valentina Studio. Some of these features are limited until you upgrade to the full version of Valentina Studio PRO. This page describes how exactly you can try a PRO feature in the FREE version.

Mac App Store version of Valentina Studio does not have any demo features because of limitations of Apple's Mac App Store policies. Download Valentina Studio from Paradigma Software to get access to the demo features.

Valentina Studio PRO adds the following major features (in alphabet order):

This feature allows you to copy records between two different databases. This feature is different from simply importing data.

Use the Data Transfer Wizard to choose one database (mySQL/postgreSQL/SQLite/Valentina/ODBC) to be a 'sources' database. Then choose another database (mySQL/postgreSQL/SQLite/Valentina) to be a 'target' database. You can then specify mapping of source/target tables and fields and load records from db1 to db2.

Taking existing databases with tables and other objects, and creating new diagram(s) is referred to as reverse engineering. You can create diagrams and add new tables, and link together with existed tables. You can save such diagrams.

You can draw totally new diagram(s) in empty database and save them to disk inside of this empty database.

FREE: You cannot ask Valentina Studio to produce SQL commands, which will create these new objects.

PRO: Buttons to generate SQL scripts are enabled. You can see that scripts. You can execute them against different databases. You can copy-paste them into your application code.

Valentina Project file allows you organize different objects into a single project. In particular, Valentina Reports, JS Scripts, Queries, etc. These objects can be organized into a hierarchy of folders and you can see project tree.

Valentina Project file can be under Valentina Server to provide multi-user access to its items and jobs.

This feature allows you to build SQL queries visually, working directly with tables and links that are a part of the query you want to create. If you aren't a SQL pro, you will find this feature invaluable!

FREE: You can create SQL queries, but you cannot copy-paste them. So you still can get help from this tool, even in free version.

Valentina Studio loads structure of database objects and their properties on demand and store in the runtime cache.
But the database structure usually doesn't change frequently as usual. This feature allows to store the schema cache and use when it is necessary.

FREE: Schema cache is removed when a database is closed.

PRO: Schema cache is saved in a file on disk, restored and used when the database is opened the next time which speeds up opening and navigation.

Valentina Studio Pro allows you to mark objects with specific colors. You can specify a color for Connection/Db/Table. After this, all tools related to this object and its sub-objects will be colorized. This allows easy differing, for example, Deployment/Development databases.

SQL Search allows you to find database objects on a server or in local storage very quickly. Objects can be located either by name or by property value, according to the filter and selected matching pattern.
